IMPROVEMENT IN APPARATUS FOR PERFORATING PAPER FOR TELEGRAPHING.

Specification ibrming part of Letters Patent No. 91,240, dated June 15, W69.

To all whom it may concern:

Be it known that I, Gnoncr: LITTLE, of Hudson City, in the county of Bergen and State of New Jersey, have invented, made, and applied touse a certain new and useful Improvement in Apparatus for Perforating or Embossing Paper for Telegraphic Purposes; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making. part of this specification, wherein- Figure 1 is a general plan of the said apparatus. Fig.2 is a side elevation with part of the bed and frame-work removed. Fig. 3 is a transverse section at the line through the punching apparatus, and Fig. 4 is a section through the hub of the actuating-lever and handle.

Similar marks of reference denote the same parts.

4 This invention is designed for perforating or embossing paper for transmitting pulsations of electricity for telegraphic purposes.

The device I have shown in the drawings is particularly adapted to the perforation or embossing of characters to represent numbers for the commercial code of signals now employed in lessening the amount of matter transmitted but the same mechanism might be employed for perforating or embossing paper for lettercharactersif the instrument were proportionately enlarged or extended.

In my instrument I make use of a lever that is swung to place, and then by 'a pressure upon it at the same time that it is-pushed forward the electric circuit is closed,- and the pulsations of electricity communicated by alternate conducting and non conducting surfaces over which the lever'passes.

- The movement of the lever, during the time the pulsations are being sent, also causes a movement of the paper the required distance for the space of the signal or letter perforated or embossed.

The perforation or raising of the paper is effected by a punch that is moved bymagnetism, and the paper is momentarilyst'oppedfor each perforation by a secondary magnet that is brought into action by the movementof the punch to stop the feed-wheel for the paper;

In the drawing, a is a bed carrying; the vertical shaft b, set in a frame, 0, at the upper end. On this shaft b isa hub, 1), around which is the eye 0 of the lever 0 and between the hub .11 and the eye cltare the clamping-segments 2 a raised segment, d, insulated from the bed a.

and the surface of said circuit-closer is formed of conducting-bars of platina or other metal, filled in between with gutta-percha or other non-conducting material.

Upon the lever c is an insulated spring, 0, with the point resting. upon the segment 01, and above thisis the screw 3.

Between the groups of conductors in the segment 01, forming the letter or number, are radial grooves,-cut as at c c.

The operator swings thelevero until itcomes to the given letter or number, as shown upon the circuit-closer segment, and as soon as the end of the spring clicks into the notch or groove 0 he depresses the end of the lever, which. brings the screw 3 into contact with the spring e, and closing that part of the circuit between the battery-wire f to the bed of the machine and lever 0 so that when the end of the spring e passes in contact with the metal conducting rib or ribs of d the proper electrical pulsations pass through the insulated segment (1, and, dividing, pass through the wires 5 5 and the coils of the magnets g g to the battery-clamping screw v6. The end of the spring dropping into the notch indicates by the touch or sound that the particular number or letter-character has been gone over, and he relieves his pressure on the handle 0 breaking the circuit between the screw 6 and the insulated spring 0, bearing down upon the lever c, clamps the shaft b, and moves that during the time that the lever is moving from one notch e to the next. This effects the movement of the paper, as hereafter described.

The adjustable roller h, taking upon the surface of the bed (I, regulates the point to which the lever maybe depressed.

I provide a blank space at d, so that the lever 0 will be brought to this point after each number is perforated, aml there depressed and moved horizontally to feed the paper without any pulsation of electricity passing through the magnets 51 y.

I provide a die, 7, at the upper end of ahollow standard, 7;, supported on the bed a, and around this is a sliding tube. I, with arms I, to the armatures m of the magnets y y. and above the arms l'a yoke, 11, carries the punch i. This yoke a has openings through itslower part at t) for the strip of paper to pass through, as seen by red lines in Fig. 3. As the magnets are charged the armatures m are drawn down and the punch i struck through the paper into thedie7. Thcarmaturesand piincharethrown up by the spring 8. Rapid punctures ot the paper will make a dash-opening, one perforation cutting into another. ])ot-perforati0ns are formed by the paper moving a short distance between the perforations. This is cffeeted by the comlucting-bars ot' the segmental circuit-closer being so arranged and spaced as to give the pulsations of electricity at the proper intervals as the lever is moved over the same and the paper simultaneously actuated.

At the upper end of the shaft I; is a gearwheel, 0, taking a pinion, 0, on the shaft p, at one end of which are the feeding-disks q 1 coming on each side of the yoke 11 and into contact with the paper that passes between them and the upper end of the standard 1:. I find that these feeding-disks are the best when each is made of two fine-cut circular saws, set with the teeth standing in opposite directions.

A spring-roller, 1', serves to press the strip of paper to the disks q and insure the proper feed of the same; and I remark that the paper might be fed in either direction, according to whether the operator presses the lever 0 down, when it arrives at the notch on the right side of the number or letter-character on the segment (I, and then moves the lever toward the left to move and punch the pa per, or whether he commences at the left-side notch and moves the lever to the right. The paper may be led as shown by the dotted red line instead of in the manner shown by the full red line.

Under the yoke 11, I place the spring-stripper 8, that has a motion limited by the pins 10, and pushes the paper off the end of the punch as the punch rises.

The standard It is held within a stationary exterior sleeve, It, fastened to the bed a, and a very slight end motion is allowed at the point 11, so that the standard I: may be pressed down against the spring t sufiiciently to allow the paper to be passedin between the upper end of I: and the disks q q.

The operation of punching the paper with perforations corresponding in position to the circuit-closers on d of the respective letters will be apparent from the foregoing, for it will be seen that the'movement of the lever 0 simultaneously makes and breaks the circuit to the punching-magnets and feeds the paper the proper distance for the perforations hence the movement will be very rapid and easily performed.

It. is necessary, however, to prevent the paper being in actual motion at the moment of the perforation,- because if it were moving the cut would not be clean, but there would be a burr raised on one side of the hole. To effect this I employ magnets in u, with loose soft-iron pins, forming self-acting extensionpoles within the magnet itself, as seen at r, and these lie close at the side of one of the feeding-disks q.

I employ an independent electric circuit from a second battery, through the bindingscrews v r, to the magnet-helix u. The spring-closer w is placed in this circuit, and the arm 14 on the sleeve lcloses the circuit to u the moment the punch descends and begins to act on the paper. The extension-poles 11 becoming magnetized instantly, attach themselves to the side of the disk q, and momentarily arrest the feed of the paper until the punch i rises suliicient to clear the paper and break the circuit at 'w.

The friction on the hub 12' allows the lever to be moved, while the feed-disks are momcntaril y stopped, or the feed-disks might tlhcmselves be mounted upon a friction-hub or t isk.

It will be seen that theextcnsion-poles become a brake to stop the feeding mechanism, and this character of a brake might be applied in other electrical apparatus.

What I claim, and desire to secure by Let tcrs Patent, is-

1. The segment (1 and lover c, constructed 'and applied substantially as specified, to give the electrical pulsations for the respective characters by the movement of the one lever, substantially as set forth.

2. The lever c, fitted to swing on the shaft b, and provided with a friction-clamp to move the shaft b and efl'ect the feed of the paper when the lever c is depressed to close the circuit, substantially as set forth.

3. The punch i, set in the yoke it upon the arms l, in combination with the vertical standardlk, carrying the die 7, substantially as set fort i.

4. The feeding-disks q, arranged to act on each side of the punch 'i against the standard 1:, substantially as set forth.

5. The standard k, sustained in the tube k, and fitted so that a slight and movement can be given to the same, in combination with the feeding-disks q, for the purposes set forth.

6. The magnet to and loose or self-adjusting extension-poles, forming a brake or stop, substantially as set forth.

7. The magnets to and extension-poles r, in

combination with the feeding mechanism, punch and circuit-closer N, substantially as and for the purposes set forth.

8. A single punch for perforating and embossing paper for a telegraphic communica- In witnesswhcreof I have hereunto-set my signature this 7th tlayot' December, A. D. 1868.
